수용액에서 Neutral red5 (BR 5)의 흡착을 조사하였다. 250oC에서 2시간동안 소각한 제지 슬러지로부터 새로운 고형 흡착제를 제조하였다. 제조된 폐수로부터 RB5 염료를 제거하기 위해 배치 시스템으로 실험을 수행한 결과, 상온 pH 5조건에서 80분동안 최대 374.98 mg/g 의 흡착을 보였다. 높은 회귀계수(regression coefficient R2)와 함께 The Freundlich isotherm이 실험값과 잘 부합하였다.

Neutral red5 (BR 5) adsorption from aqueous solution was investigated. New solid adsorbent was prepared from paper sludge incinerated at 250oC during 2 hours. Experiments were carried out, in batch system, to remove RB5 dye from the synthetic waste water. Maximum adsorption of 374.98 mg/g at pH 5, at room temperature and contact time of 80 min was obtained. The Langmuir and Freundlich adsorption models were applied to interpret the equilibrium isotherm. The Freundlich isotherm fits quite well with the experimental data (with highly regression coefficient R2). The incinerated sludge solid samples untreated and treated with BR5 dye were characterized by FT-IR spectrophotometer.
